The xylem of anthesis flower parts and pedicels
consists exclusively of tracheary elements with helical bands, and rarely, with annular bands.
Flowers can be brought to the lab for later use, and the pedicels
should be kept in water.
Each antenna was comprised of a scape, a pedicel
and a flagellum (Fig.

white setose dorsally, asetose ventrally; postpedicel cylindrical in proximal half, symmetrically bulbous in distal half, [greater than or equal to] 3.
Vegetti (1994, 1999) proposes the following process to determine these variations: (1) reduction of the structure and the number of the inflorescence short branches (the maximum reduction of the subzone of short branches occurs in Anadelphia trichaeta Clayton, which consists of just one sessile spikelet and two reduced pedicels
, and in some inflorescences of Cleistachne Benth.
Treatment of 8 ml ethanol/kg grapes on impregnated paper controlled 98% of the decay, although the ethanol applications caused visible stem and pedicel
Scanning electron micrographs were taken of the area around the pedicel
from a standard view (normal to the pedicel
axis) and other angles when deemed useful.
Antennal scape blackish brown; pedicel
yellow; 1st flagellomere pale brown except yellow at base, nearly 1.
5m; floral bracts like scape bracts, to 8cm, about equaling pedicels
ascending, stout, to 7 cm long, green at anthesis, drying dark brown.
Head (Figs 1, 2): Ground colour dark on vertex, occiput and postgenae, light ochre-yellow on frons, parafacials and genae, covered in light grey to silvery grey dusting; antennae brownish black or to varying extent orange-brown to orange-yellow on scape, pedicel
and basal part of postpedicel; palpi brownish black, on basal half often ochre-yellow dorsally.
The results also indicate pedicel
